<br />"i <br /> <br /> <br />sUMMARy <br /> <br />o <br />(.-' <br />," ) <br />00 <br />N <br />00 <br /> <br />Exports, principally generation from coal-fired steam-electric plants, <br />will be 13,400 Mil in 1980 and at the level of 39,500 MN' in 2000. After <br />the year 2000. the amount of power exported will decline because of a <br />lessened demand by importing areas. Both the Lower Colorado and Califor- <br />nia Regions show a marked decline in energy :imports from the Upper Colo- <br />rado Region. The annual consumptive use of water by steam-electric gener- <br />ating capacity will reach the ultimate of 630.600 acre-feet per year by <br />2000. which is 27 times the amount consumed in 1965. Program invest- <br />ment costs (federal and nonfederal) of power plants and transmission lines <br />developed in the Region are estimated at $2.2 billion between 1966 and <br />1980, and $5.2 billion between 1981 and 2000. There are no program addi- <br />tions predicted for the 2001 to 2020 period. <br /> <br />Operation, maintenance. and replacement annual costs associated <br />with the incremental investment programs for the respective time periods <br />1966-1980 and 1981-2000 are $197 million for the target year 1980, and <br />$438 million in 2000. Production of steam-electric energy will be re- <br />duced between 2001 and 2020., with a consequent decrease in energy fuel <br />costs: therefore, there will be a reduction of $43.4 million in operation. <br />maintenance,and replacement annual costs in the target year 2020. <br /> <br />Three alternative regional plans were developed that reflect em- <br />phasis on different uses for the available water supplies and resources. <br />The states' adjustments in the amount of steam-electric capacity in- <br />stalled in the alternatives as compared to that developed for the OBERS <br />plan are: (1) in the states' alternative to the framework plan (6.5 mil- <br />lion acre-foot) level of development, 510 megawatts were added: (2) in <br />the states' alternative at the 8.16 million acre-foot level of develop- <br />ment there was a regional increase of 5,510 megawatts: and (3) in the <br />states' alternative for water supply physically available at site in the <br />region there was a total increase of 8,310 megawatts in the amount of - <br />steam-electric generating capacity installed. <br /> <br /> <br />iv <br /> <br />
